  • Dampwood – This type of termite are commonly found in damp woods and are seldom found in homes. They belong to the Hodotermitidae and Kalotermitidae families.
  • Conehead – Conehead termites usually gather in the open and there are likely to build their nests in trees.
  • Subterranean – These termites build large nests and live in the soil. Commonly found in the U.S., this type is considered to be one of the most destructive insects. They can destroy house foundation faster than drywood termites.
  • Formosan – This type of termite is more aggressive when it comes to defending their nest than subterranean termite soldiers. They nest and invade structures within the soil.

Any of these types may be present in your home, garden or backyard. Some signs of termite infestation include cracked or bubbled paint on walls, wood damage, small wings on the floor or at any corner of your house, and hollow sounds on solid wood.

How to Kill Termites?

There are many things that can kill these annoying pests. Certain chemicals can instantly purge a colony of termites. Because of their capacity to cause huge destruction, it is recommended to call a professional to get rid of infestations.

There are also simple and effective techniques on how to kill termites yourself. Here is a list of the best solutions on how to eliminate these annoying pests.

1. Identify the Type of Termites

The two general types that might invade your home are drywood and subterranean termites. Drywood termites live solely in wood while subterranean are found in both wood of homes and soil around the area.

Subterranean termites do more damage to home foundation than drywood so it may need different solutions. You will also need methods that can kill these termites as quickly as possible, such as nematodes and borax.

Aside from the wood of your home, these termites may also infest compost piles.

2. Borax

Also known as sodium borate, borax is one of the best solutions on how to kill subterranean termites. It leaves them dehydrated and shuts down their nervous system.

You can also use this for other types of termites.

  • Dust or coat infested areas with borax. Repeat the application daily for a few weeks until you kill all termites.
  • Another method on how to kill termites with borax is by adding 1 teaspoon of this powder with 8 ounces of warm water. Mix it well and transfer the solution into a spray bottle and sprinkle on infested wood, furniture, walls and other items. Repeat this treatment once or twice daily.
  • You can also paint a borate solution onto wood surfaces to prevent future infestations.

Note: Wear a mask and gloves while using borax. This can be toxic when inhaled. Keep the power or spray away from children and pets.

3. Orange Oil Spray

One of the best ways to kill drywood termites is by spraying orange oil on them. It is also highly recommended by experts as it contains D-Limonene that can lead these annoying creatures to their demise.

That compound is also what gives oranges and other citrus fruits their pleasant scents.

To use this method, you will need orange oil and a small spray bottle. Here’s how to kill flying termites and those hiding in wood.

  • Pour orange oil into a spray bottle. Spray it on flying termites and all areas where these insects are hiding.
  • You can also apply orange oil directly to infested furniture to kill termites. Many people also drill small holes into woods and inject orange oil. Repeat the applications for several days until there are no more signs of infestation.

Orange oil is also effective against mosquitoes, crickets, mites, and flies.

4. Parasitic Nematodes

Nematodes are worm species that can kill a whole colony of termites. If you are having problems with subterranean termites, you can exterminate them quickly with this natural method.

These parasitic roundworms enter the bodies of termites and feed on it. Bacteria are then released from nematodes’ guts. Termites will soon die from blood poisoning caused by these bacteria.

  • Add beneficial nematodes into a pail of water. Mix and let it sit for five to ten minutes. Pour the solution into a spray bottle. Shake and spray where you have seen infestations.
  • Once all termites are dead, nematodes will look for their next target. This means that they help control infestations and keep other insects at bay.
  • If you will use beneficial nematodes on infested soil, make sure that you spray them after sunset or early morning as sunlight will kill them.
  • Beneficial nematodes are not harmful to humans, plants, and pets. These worms only focus on insects, so they can destroy their entire colony in just about 48 hours.

    5. Permethrin Dust

    Permethrin is a synthetic chemical used for controlling subterranean and other types of termites. It is similar to the natural pyrethrum insecticide that derives from chrysanthemum plant, but it lasts for extended periods of time.

    1. Wear a mask before using diatomaceous earth.
    2. Apply a thin layer of diatomaceous earth on infested furniture, walls, ceiling, soil, and other areas that may be pest-ridden.
    3. Sprinkle this powder once in a while to prevent termites and other insects from coming back.

    This technique may take a few days, but it works effectively.

    7. Neem Oil Spray

    Neem oil is obtained from the seeds of neem trees. In addition to its incredible health benefits, this oil is also used as an organic insecticide spray. It acts as a repellent and reduces insect feeding by interfering with their hormones. This makes it hard for pesky creatures to develop and lay eggs.

    1. Place infested furniture in direct sunlight.
    2. Leave it outside for three to five days.
    3. Expose other items that may have termites.

    Combine this method with other termite traps to speed up the killing process. If sunlight is not strong enough in the area, UV lights that copy sunlight may be effective.

    9. Wet Cardboard Bait

    A wet cardboard is one of the effective solutions on how to kill termites naturally. Because termites feed on cellulose, the woody smell of wet cardboard will be appealing to these insects.

    1. Take some cardboard strips and make them wet.
    2. Stack them near the infested areas. Termites will smell the scent of wet cardboard and feed on its cellulose. Leave it overnight.
    3. Once the cardboard is infested with these insects, use gloves and take it outside.
    4. Burn the cardboard immediately to kill the termites.
    5. Repeat this method as many times as necessary.
